DUMPING-CAR.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed May 18, 1908. Serial No. 433,481.

To all whom it may concern:

Be'it known that I, MAX ORENSTEIN, a

citizen of the German Empire, residing at conveyance of sand, earth,stones and the.

like, the bodies of the various cars must be tipped in succession byhand.

The subject of my invention is a'contriv ance by means of which the workrequisite for tilting the car-bodies is performed by the locomotiveemployed to draw the train of cars, the bodies of all the latter beingtipped automatically during running of the train.

The accompanying drawing, by way of example, shows the invention appliedto dumping-cars tilting to one side only.

Figure 1 is a side elevation of a box-bodied dumping-car. Fig. 2 is afront elevation and part section thereof. Fig. 3 is a side elevation ofa modification. Fig. 4 is a front elevation thereof. Fig. 5 shows thetiltinglevei" alone.

, The car itself, with its body, may be of any well-known constructionand shape.

The lmprovement consists ineach car being furnished with coupling-parts,by means ofwhich the car-body can be coupled with one of therunning-wheels of the car (or with a wheel, lever, or the like, actuatedby a running-wheel), and by means of which,

after coupling has been effected, a moment of torsion sufficient fortilting the car-body is transmitted to "the latter by push or pull.

In the car shown in Figs. 1 and 2 a tiltinglever b is secured by meansof a cross-joint c to the bed of the body at on the side opposite tothat at which the contents are dumped. Ordinarily the lever 12 is heldoutof use in the horizontal, dotted-line position shown in Fig. 1 by ncans of a suitable catch 0. To the free end of the lever b there isjointed a pin f. In the wheel a a number of holes 9 are drilled orotherwise provided at equal distances apart, into which the pin f fits.The length of the lever b is such that when the body is in itsnon-tilted position the in f can be inserted into that hole 9 whic forthe time being is the lowermost.

As each car in succession arrives at the place of dumping, the body atand wheel a must be coupled by the lever b as described. If now thetrain of cars is drawn forward, or pushed backward, by the locomotive,then on the wheel a of each car after cou ling making half a rotation,the body (I Wll be tilted with positive motion into thedottedlineposition shown in Fig. 2. If the train of cars is drawn through adistance represented by more than half a rotation of the wheel, forinstance, by several rotations, the body will not only be tiltedforward, but will be tilted I back again into the normal position, orwill be tilted to and fro several lLlIIIBS, whereby a better guaranteeis offered for complete dumping of the contents of the car.

Between the coupling-parts there may be a suitable amount of play left,so that the body (1, when once lifted beyond its position 'of unstableequilibrium, can drop lnto the end position by gravity.

Instead of connecting the body cl with the bottom of the wheel a bymeans of a member exerting a push (tilting-lever b) on the side oppositeto that at which the material is dumped, the body (1 may be connectedwith the top of the wheel on the dum ing side itself. In this event thetilting is one by a ull instead of a push. If in such case there isemployed to connect the body (Z and the wheel a a member '(for example achain) which can only be used to exert a pull, but not a push, then thecar-body will only be tilted forward, but not backward again, so thattilting to and fro cannot be effected.

In the modification shown in Figs. 3 and 4 the body d is not connectedwith a wheel a direct, but with a disk m presenting holes Z and drivenby one of the wheels (I, by means of suitable gear, such as toothedwheels 71,, i, Tl

It, or chains.

Having thus described my invention, I claim as new:

1. In a dumping car, a frame, car wheels upon which said frame ismounted, a trans- Vorscl y tilting body pivoted to the frame, and a barconnecting the tilting body with one of the car Wheels where byrotationof the wheels in either direction will tilt and afterwardsreturn the body to its normal position.

2. In a dumping car, a frame, oar wheel's upon which said frame ismounted, a transversely tilting bod y'pivoted to the frame, and

direct connections between the tilting body and one of the car wheelswhereby rotation .l. l (i ver whose upper end is ointod to one side ofof the wheels in either direction will tilt and afterwards return thebody to its normal position. I

3. In a dumping car, a frame, car Wheels upon which said frame ismounted, a transversely tilting body pivoted to the frame; andnon-flexible connections between the by rotation of the wheels in eitherdirection its normal position.

4. In 3, dumping-our, a tilting body and car wheels on which it Ismounted, and a le- E tachably 1 wheels wi gposition, whereby on rotationof the said 5 wheel the lever is raisedend tilts the car bodyautomatically, substantially as de- 20 i scribed.

tilting body and one of the emwheels where 5 l the said body and whoselower end can be de- 15 ointed to a point on one of the can ien suchpoint is in its lowermost In witness whereof I have hereunto set my 5hand in presence of two witnesses. wlll all; and afterwards return the.body to MAX ()RENSTEIN.
